Micro TIG Welding

Micro TIG processes focus on welding small parts with an area of 5 mm x 5 mm. These are usually delicate parts in the automotive, medical, or electronics industries. Pulsed-arc welding has many advantages. For example, it is a solder-free process and the resultant weld is highly durable when exposed to vibration and heat. In addition, pulsed micro TIG welding is used widely for joining high melting point metals, dissimilar metals, and even thin magnet wires of φ0.02mm.
